Sedat, I ran into this a few years back and could not find any acceptance criteria ( mil or IPC) for flex re-work, this may have changed by now. Anyway I wrote a procedure that was accepted by Raytheon QA. Use stranded Kevlar insulated wire, tack-pak it to follow the original trace, laminate the wire to the surface with Kapton tape. Terminate the way you would on a rigid PCB. This was approved for single/service flex applications, not repeated flex applications. Hope this helps.
